A magnetron-specific phase-locking model has been developed using the standard equivalent-circuit approach which takes into account the unconventional magnetron growth characteristics as well as the frequency pushing effect. These effects owe their origin to the highly nonlinear electron-wave interaction thus are believed to be more pronounced in relativistic magnetrons. The model predicts a wider locking-bandwidth and a shorter locking time than those in conventional locking theory. The phase-locked amplitude resonance occurs as the results indicate at an injection frequency different from that of the free-running oscillator. 1.
